摘　　要：对北京某区域低中压管网于2016~2020年间的管道腐蚀泄漏数据进行了统计,对腐蚀影响因素进行了分析。结果表明:管道外防腐蚀层类型、压力等级及阴极保护状态,杂散电流强度等因素对管道的腐蚀泄漏都具有重要影响,且阴保状态及外防腐蚀层种类的影响最大。Based on the statistics of pipeline corrosion leakage data of a regional low and medium pressure pipeline network in Beijing from 2016 to 2020,the corrosion influencing factors were analyzed.The results showed that factors such as the type of the external anti-corrosion layer,pressure level,cathodic protection status,and stray current intensity of the pipeline had important effects on the corrosion leakage of the pipeline.The cathodic protection status and the type of the external anti-corrosion layer had the greatest impact.
